Strainers and filters are essential components used in pipelines and fluid systems to remove unwanted particles, debris, and contaminants from liquids or gases. They help protect pumps, valves, meters, and other equipment from damage caused by impurities.

A strainer typically uses a perforated or mesh screen to trap larger particles such as rust, dirt, and scale. A filter, on the other hand, is designed to remove much finer particles, ensuring cleaner fluid flow and improved system performance.
